PEN.

Application filed February 4, 1926. Ser1a1No.'- 86;0(l2..

The invention relatesto improvements in' pensor. .metal'. paint brushes? of the type used primarily for printing signs, wide nibs being. provided-toproducea wide line when 5 thekpenis moved in one-direction and a relatively narrow line when-moved in. a. transverse-direction.

It is one object of the invention to provide-- a pen ofv the character described in which novel provision. is inadefor securingan upper, resilient nibtoithe body of the pen.

7 Other obj ects' are to make unique provision for-varying-the tension with which the uppernibis held againstthe lower nib, and-to 1 providea novel association of parts, whereby the. upper. nib may beadjusted forwardly orv rearwa-rdly: to the most advantageousposition.

Yetanother aim is to provide a pen which willbe; rather; simple and inexpensive, yet will be eflicient and in every way desirable.

With the foregoing inview, the invention,

resides'in the novel subject matter hereinafter described and claimed, the description beingrsupplemented by the accompanying drawings.

portion of the pen, having. a trough-like front end portion 13 and areservoinld' be-i hind and communicating; withI said trough.-

likev portion tocontain the. ink. or paint.

The front end of the portion 13; forms a:

stationary" lower nib 15,;and;the:side. walls 16 for said troughrlike-portion.maywell cont-inuations. of the reservoir side walls- The rear end of the body 12 is formed with a socket 17 in which the'front end of the, handle l8-is.secured,-the. top: 19. of said. socket. being flat and longitudinally :dis, posed and having upstanding flanges, 2O at; itsside edges, formed by continuations of."

the. reservoir-side walls. In the present.

showing-La bridge 21 extends between theupper edges of the flanges 20, over the.

front part of: the socket portion 1,9,and a.

finger-operated screw 22, is threaded through: this; bridge, saidscrew having a plate 23 swiveledto its lowerend- Received betweenthe side walls of the res,-

ervoir 14, the side walls 16 ofthe trough? like portion 13, and the flanges 20, is anupper, resilient, longitudinally disposed up.-

wardlybowed nib24, said nib. comprising-a; strip of spring metal which is. reinforced:- andstiffened fromits rear endto a-point' spaced rearwardl from its frontiextremity,

by longitudinal anges 25v which. mayeither be suitably secured to theedge. portions of. the springmetal strip, or may. be 'formedby;

upwardly bending said edge portions. The front portion any reinforcing means, sothat it. may readily. vyield.

The rear part of the nib 24 is receivable between the p1ate-23 and the socket portion 19, and'unde'r normal circumstances, that is before thevscrew- 22 isappreciablytightened, said nib and said socket portion'19Qconverge.v rearwardly asshowninv Fig. to a point oft contact which isat the rear end'of the'nibr- The downwardly curved front portion. 26. then rests on and-turns downwardly infronti of the .stationarynib 15' as shown in Fig. 2. By tightening the: screw 22', the. stifl'ened 26 of the. nib 24.. is freeof of the nib 24. may be forced downwardly, and thenihend26 isgradually placed under greater tensionrassuch tight.

ening is effected. Thus, the nib end 26 may be held against the stationar nib 15 with any adequate degree of tension, according to the work being done and the quality of the liquid used in the pen. Pressing of the front extremity of the nib end 26. against the paper or other surface upon which printing or the like is being done, causes said nib f end to yield upwardly from the stationary nib 15, permitting the liquid to flow.

The nib 24, it will be observed, may be slid forwardly or rearwardly and thus adjusted to produce the best results,-and for producing such-adjustments as well as for easily removing and re-applying the nib when necessary, it is provided with an ap propriate handle 27.

In Figs. 4; and 5, two pen units U and U are shown, mounted upon a common handle 18. The unit U is identical with the pen structure above described, theunit U is pivoted to said unit U as indicated at 28, and

an appropriate spring 29 normally swingssaid-unit U upwardly as shown in Fig. 4. When its use is desired, however, it may be swung downwardly against the action of the spring to the limit permitted by an appropriate stop 30. One of the units is preferably rather wide and the other comparatively narrow, so that spaced lines of different widths may be made with this form of construction.

"In Figs. 6 and 7, a pen body 12 is provided, having a relatively'large and wide reservoir 14*, said reservoir having a top 19 extending forwardly a suitable distance into adjusted position, against the top 19.

Whereas, in the form of construction disclosed in Figs. 1 to 5, it is necessary to totally or partially remove the upper'nibto fill the reservoir 12, the reservoir 14 is provided with a filling neck 32 closed by an appropriate cap 33. In Fig. 8, the general proportions of the body 12 are about the same as in Figs. 1, 2 and 3. The reservoir however, is provided with atop 19 which extends forwardly into the trough-like portion 13 to the extent shown by dotted line L. The upper nib 24 of resilient nature, rests upon this top wall in the same manner as nib 24 engages the wall 19. This nib is formed with a longitudinal slot 31 similar to the slot 31, and a clamping and adjusting bolt 22 passes through this slot and through the top 19 of the reservoir.

Fig. 10, illustrating an upper, resilient nib 24$, merely discloses the fact that in stead of employing a slot such as 31 or 3l",

a slot 31 1nay be employed, having an enlarged end 31 of a size to receive the nut of the bolt 22? or 22".; Thus, when the nibis to be removed, it is simply necessary to loosen this nut and slide saidnib until alinement of the enlarged slot end with the nut of the bolt, permits easy removal of the nib, without the necessity of entirely removing the nut from the bolt. T

' Fig. 11, illustrating a portion of a nib 24, illustrates liquid discharge grooves 34 formed in the lower face thereof and posi- 78B tioned as desired,for the purpose of feeding a surplus of. ink at one portion or another of the pen, so that shading effects may be readig;

This detail may. be used in 1y produced. connection with any form of construction herein illustrated, and obviously, the nib may be of any desired width, according to the character of the work to be done.

The numerous uses of pens such as thatherein disclosed, are too well known to re-- quire explanation herein, and it will be ob vious to those skilled in the'art, that I have produced an exceptionally simple and inexpensive pen, yet one which will be eflicient and in every way desirable. As excellent re sults have been obtained from? the general" construction disclosed,'it is by preference followed. However, within the scope of the invention as claimed, variations may be made; I

I claim 1. A pen comprisingan elongated'upp'er 'lOC nib of resilient material, a pen bodyhaving a trough-like portion between whose side walls said nib is received, said body having a substantially flat surface underlying the rear portion of said nib, said surface and said rear portion of the nib convergingrear-- 'wardly to a point of contact, and means in advance of said point of contact for spring ing the nib to place it under desired tension,

the front end of said nib resting upon and being downwardly turned in front of said trough-like portion ofsaid body. v

A pen of the class describedcomprising an elongated body of trough-shapein transverse section and provided with a rearward 1y opening handle socket at its rear end, the upper side of said socket being down-, wardly spaced from the upper edges ofthe body side walls, a transverse bar spannin said sidewalls, secured t-hereto'and space above said upper-side of said socket,-an elongated upper nib. of resilient material, reclamping screw threaded through said trans ceived between said side walls and having verse bar for clamping said upper nib its front end turned downwardly in contact against said upper side of said handle 10 V with the front end of the bottom of said socket.
